bird-cli

A terminal guide for Bird, a command-line program that connects to the Bird communications service. Bird supports operations for email, SMS, and WhatsApp, but requires API credentials.

In plain words
What is it for?
Sending and inspecting messages, managing reusable email or SMS templates, checking sending domains and delivery settings, and verifying whether a WhatsApp number can receive messages.
Why use it?
It provides a defined path for installing, authenticating, and choosing the right command for communications tasks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

bird-cli scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Bird CLI

bird is a single binary that talks to the Bird API. Each top-level command is one operation; every operation talks to the live API, so all of them need credentials first.

If bird isn't installed (command -v bird finds nothing), install it first — a checksum-verified download to ~/.local/bin (or /usr/local/bin):

curl -fsSL https://cli.bird.com/install.sh | sh

The path

Step 0 — Authenticate (shared prerequisite). Every command below fails without a key, and the failure looks the same as a real error, so confirm credentials first: authenticate. It is a no-op when bird auth status already reports valid: true, so it is safe to run first every time. No account yet? Create one — account, organization, and workspace — from scratch: onboarding; it ends by storing the same credential a login would.

Step 1 — Run the operation the user asked for:

  • Send or inspect email messages (bird email, including send-batch) → email
  • Author reusable email templates, submit a draft, or roll one back (bird email templates) → email-templates
  • Send or inspect SMS messages, or browse SMS templates (bird sms) → sms
  • Draft the carrier verification a US toll-free number needs before it can send, read what the carrier asks for, or see why one was declined (bird sms tfn verifications) → tfn-verifications
  • Claim an alphanumeric SMS sender, find out what a country requires of it, or register it for a country (bird sms senders) → sms-senders
  • Send or inspect WhatsApp messages, follow a message's events, connect or manage the numbers and business accounts the workspace sends from, check whether WhatsApp will accept a number before buying it, or read WhatsApp traffic statistics (bird whatsapp) → whatsapp
  • Browse WhatsApp templates, their versions, and each version's per-language content (bird whatsapp templates) → whatsapp-templates
  • Inspect voice calls, find out why one was refused, configure a SIP trunk or an inbound number, enable or disable calling to a country, or place a test call (bird voice) → voice
  • Provision Realtime apps and rotate the keys their clients connect with (bird realtime) → realtime
  • Verify a recipient with a one-time passcode — send a code, then check what they submit (bird verify verifications) → verify
  • Find out about a recipient before you use it — grade an email address, or identify a phone number and its network (bird lookup) → lookup
  • Manage contacts, audiences, and contact properties (bird contacts, bird audiences, bird contact-properties) → contacts
  • Record and look up messaging consent grants and opt-outs (bird preferences) → preferences
  • Manage sending domains (bird email domains), or find a verified from to send from → domains
  • Count how much mail the workspace received, by period, day or hour (bird email stats inbound) → received-mail-stats
  • Style the hosted page a marketing recipient lands on when they unsubscribe (bird email unsubscribe-page) → unsubscribe-page
  • Manage dedicated IPs (bird email dedicated-ips) and IP pools (bird email ip-pools) (sending reputation) → ip-pools
  • Receive email at inbound forward addresses (bird email inbound-addresses), or read the mail received there (bird email inbound-messages) → inbound
  • Manage outbound webhook endpoints → webhooks
  • Issue a workspace API key (bird api-keys create) → api-keys (needs a login carrying api_keys:write; an API key cannot run it)
  • Find out why acquiring a number or registering a sender was refused for a reason about the organization rather than the country, and settle the requirement behind it (bird trust) → trust
  • Find the business a 10DLC brand is registered for, so brands create can name it (bird compliance identities list) → compliance-identities
  • Register a 10DLC brand for US A2P traffic, or file a submission against one (bird sms 10dlc brands create, bird sms 10dlc brands submissions create) → sibling operations; node not yet authored, --help on each carries the field list
  • Open a support ticket, reply to it, or wait for a support agent reply → support
  • Answer a how-to or reference question about Bird from the documentation → docs (public — skips Step 0)
  • Inspect resolved CLI configuration → bird config show (sibling operation; node not yet authored)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

bird-cli is a skill published in the GitHub repository messagebird/bird-ai (1 stars, last pushed yesterday), licensed MIT. It adds 201 tokens to every session and 1,661 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
